I particularly enjoyed your “Setting Up A Binder” article in the last Small Farmer’s Journal. I noticed that the Champion binder has an IHC auto-steer tongue truck. I’m wondering if you know when that Champion binder was manufactured. There are many clever designs in the old horse machinery, but I have long admired how that tongue truck turns shorter than the tongue so a team can sidestep around a corner to line up for the next swath. We had one of these tongue trucks installed on a #9 mower back when Dad was still alive and farming. I still have a couple stashed in my windbreak.
The driller is like an auger type post hole digger powered by one horse walking around the machine. The gear is stationary. The platform and everything on it (including operators) goes around and around with the horse. The auger shaft is clamped to the platform so the auger makes one revolution as the horse makes one revolution. The gears operate a winch. It appears the winch can also be cranked by hand.
